Right turn signal broken due to loose column

[Montierth]

I have a column shift automatic non tilt original steering column. Has anyone had the problem where turning left the blinker turns off by itself as it is supposed to but when turning right it will not turn off? What I found out is that if I push up on my steering wheel (taking up all the play from wear over the years) then it will turn off the right turn signal. I have examined all the internals and all work fine and are not broken from what I can tell. What parts in the column would I replace to remove all the slack or looseness of the steering wheel?
